The equation y = 700x + 800 models the typical annual cost, y, in dollars, of medical expenses x years after a person’s 20th birthday. What does 800 represent?

Answer:

I think its 1200 not sure though

Answer:

1,200

Step-by-step explanation:

first you would divide 480 copies by 4 minutes to see how many copies per minute (120) Then you would take 120 copies per minute and multiply it by the 10 and you would get 1200 copies per 10 minutes! lmk if that helps:)

Answer:

196-49 pi

Step-by-step explanation:

diameter of circle is 14

radius-7

7^2=49

49 pi

14^2=area of square

196-49pi= area of shaded area.

Answer:

im pretty sure the area is 196

Step-by-step explanation:

because when finding the area of a rectangle/ square you use the formula Length * Width and as we can see the sides of the shaded are are equivalent and as we know the length of the shaded area is 14.

we would just plug in our information.

L*W

14*14= 196

Step-by-step explanation:

Answer: The width of each flag = 12 cm

The average amount of time it takes Sandra to make each flag =  20 minutes.

Step-by-step explanation:

Given: The ratio of the length to the width the official german flag is 5:3.

Let length = 5x, width = 3x

Length of each flag = 20 cm

i.e. [tex]5x=20\Rightarrow\ x=\dfrac{20}{5}=4\text{ cm}[/tex]

Then width of each flag = 3 x 4 = 12 cm

i.e. width of each flag = 12 cm

Total time to make 12 flags = 4 hours

Time taken to make 1 flag = [tex]\dfrac{4}{12}[/tex] hour

Time taken to make 1 flag = [tex]\dfrac{1}{3}[/tex] hour

1 hour = 60 minutes

Time taken to make 1 flag = [tex]\dfrac{1}{3}\times60[/tex] minutes = 20 minutes.

Hence, the average amount of time it takes Sandra to make each flag =  20 minutes.

Step-by-step explanation:

i took the test

The required length of one side of the given regular pentagon is  5 units.

Polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,
We can use the formula for the area of a regular pentagon to solve for the length of one side,
Area = (1/2) * Perimeter * Apothem

Since the pentagon is regular, all sides are equal, so we can write:

Perimeter = 5 * Length of one side

Substitute in the first expression

50 = (1/2) * 5 * Length of one side * 4

50 = 10 * Length of one side

Length of one side = 5

Answer:

y = 7 and x =3

Step-by-step explanation:

use elimination method

so we gonna eliminate y first

9x = 1 - 4y

-7x = -7 + 4y

7| 9x = 1 - 4y

9| -7x = -7 + 4y

63x = 7 - 28y

-63x = -63 + 36y

add eqtn 1 to eqtn2

you will get

0 = -56 + 8y

56 = -56 + 56 + 8y

56 = 8y

56÷8 = 8y÷ 8

7 = y

also eliminate x as we have done wth y

4| 9x = 1 - 4y

4| -7x = -7 + 4y

36x = 4 - 16y

-28x = -28 + 16y

add the two equations

u will get

8x = -24 + 0

8x = -24

8x÷8 = 24÷ 8

x = 3

Answer:

[tex]y = 4(2^{x} )[/tex]

Step-by-step explanation:

The general form for an exponential function is [tex]y = kb^{x}[/tex]

When x = 2,  y = 16    So, [tex]16 = kb^{2}[/tex]    

and when x = 3,  y = 32    So, [tex]32 = kb^{3}[/tex]

Divide  [tex]\frac{32}{16} = \frac{kb^{3} }{kb^{2} }[/tex]

2 = b

Now, [tex]16 = k2^{2}[/tex]

16 = 4k

k = 4

Therefore, the exponential function is [tex]y = 4(2^{x} )[/tex]

Where x represents the previous year's salary, its amount this year is said to be ...

  x + 2000

The equation is trying to reflect the fact that 7% of that is $3,290. The missing number is 2000:

  0.07(x +2000) = 3290

__

Solving for x, we find ...

  x = (3290/0.07) -2000 = 45000

Sandra's salary the previous year was $45,000.

Answer:

3ft

Step-by-step explanation:

We are given that

Height of lamp, h=12ft

Height of shadow, l=6ft

Height of shadow of hydrant, l'=1.5ft

Let height of hydrant=h'

We have to find the height of fire hydrant.

All right triangles are similar

When two triangles are similar then, the ratio of their corresponding sides are equal.

Using the property

[tex]\frac{h}{h'}=\frac{l}{l'}[/tex]

[tex]\frac{12}{h'}=\frac{6}{1.5}[/tex]

[tex]h'=\frac{12\times 1.5}{6}[/tex]

[tex]h'=3[/tex]ft

Hence, the height of fire hydrant=3 ft
